centos 下Supervisor 守护进程基本配置

supervisor:C/S架构的进程控制系统,可使用户在类UNIX系统中监控、管理进程。常用于管理与某个用户或项目相关的进程。

组成部分
supervisord:服务守护进程
supervisorctl:命令行客户端
Web Server:提供与supervisorctl功能相当的WEB操作界面
XML-RPC Interface:XML-RPC接口

安装

easy_install supervisor

创建默认的配置文件

echo_supervisord_conf >/etc/supervisord.conf
vi /etc/supervisord.conf

修改配置文件如下,这个例子设置了一个Nginx和asp.net core的守护进程

[program:WebApp1MVC]

autostart=true
autorestart=true
stderr_logfile=/var/log/hellomvc.err.log
stdout_logfile=/var/log/hellomvc.out.log

autostart=true
autorestart=true
stderr_logfile=/usr/local/nginx/logs/nginx.err.log
stdout_logfile=/usr/local/nginx/logs/nginx.out.log

关键配置如下:

 [program:WebApp1MVC]
command=/usr/bin/dotnet /home/wilson/temp/PublishOutput/WebApp1.dll
directory=/home/wilson/temp/PublishOutput/
autostart=true
autorestart=true
stderr_logfile=/var/log/hellomvc.err.log
stdout_logfile=/var/log/hellomvc.out.log
environment=ASPNETCORE_ENVIRONMENT=Production
user=www-data
stopsignal=INT [program:Nginx]
command=/usr/local/nginx/sbin/nginx
directory=/usr/local/nginx/
autostart=true
autorestart=true
stderr_logfile=/usr/local/nginx/logs/nginx.err.log
stdout_logfile=/usr/local/nginx/logs/nginx.out.log
user=wilson
stopsignal=INT

启动Supervisor

supervisord -c /etc/supervisord.conf

浏览器中输入http://127.0.0.1:8888,输入用户名密码,就可以看到后台进程列表
